Close-up photos of the hats can be found in my crochet gallery.
The beanie (far right) was definitely the easiest to make, but it isn't very warm. I really like the green hat, but it's too big for my head. Jon likes the hat on the far left, so I will be starting another version of this hat using the new yarn I purchased (Red Sox colors) in Massachusetts.
If you have a favorite crocheted hat design, let me know!
